you know what you are doing and the market is real, you can predict well you make money, that's how it goes.
I'll choose trading overtime although I love to improve my skills in gambling but I need to choose which would I spend my time more.
since gambling and trading is have a risk, then we need to determine what we want to do. maybe if one person is good with skill based gambling, he choose to playing gambling but the other person will choose doing trading because he can make a nice profit in trading. i think gambling and trading have risky, both have the same chances to make big profit too.
